Local project guide
Earlsfield's terraced houses are well suited to side-return, rear-extension and loft projects, but shared walls and compact access make preparation important. We survey the house as a whole and set out the consent, structure, services and finish decisions before agreeing a fixed scope.
Completed work
Earlsfield sits between Southfields and Wandsworth Common. It's mostly Victorian and Edwardian terraces, which means a lot of side returns and lofts, and a lot of shared walls.
The brief was a wider kitchen and somewhere for the family to sit down and eat. We filled in the side return, added about 200 sq ft and handed it back in eight weeks.
Bi-fold doors open the room onto the garden, and there's underfloor heating under the new floor. Underfloor heating works well in a side return. Once the room is all doors and kitchen units, there isn't much wall left for a radiator.
Side passages often have a drain running along them. If it's a public sewer, building within three metres of it needs a build-over agreement from Thames Water, and you have to apply before work starts. We try to find out where the drains run early on, so it isn't a surprise once the digging starts.
A side return also tends to go right up to the boundary, so next door gets a party wall notice. Do it early, because the notice period sets the earliest start date.
Not all of Earlsfield is Victorian. The Magdalen Park conservation area is built around two council estates from the early 1930s, Openview and Fieldview. The Fieldview blocks are two-storey flats that were designed to look like terraced houses. If you're in one, you own a flat, and a flat doesn't get the permitted development rights a house has. Check before you plan a loft.
On a mid-terrace everything comes through the front door: steel, blocks, plasterboard, the kitchen. We usually sheet the hall and stairs at the start and try to time deliveries so the skip isn't on the road longer than it needs to be. Earlsfield is Wandsworth borough, so skips and scaffolding need council licences, and we aim to apply in good time.
For a loft, our nearest job is the dormer conversion in Southfields, just to the west.

Typical project build prices, excluding VAT and professional fees (design, structural engineer, Building Control, party wall and planning fees). Prices are the same across every borough we cover; access and logistics (parking, skips, scaffold, restricted access) can affect the final price. Your fixed quote follows a site visit.
